I am starting my first extended water fast today for 21 days. I’ve completed 16 hours to 24 hour fasts a number of times, and wanted to start this prolonged one. If I use a pinch of pink salt and a tablespoon of Apple Cider Vinegar a day, diluted by a 1.5 liter bottle of water, will that negate the water fast benefits? I want to make sure my electrolytes and potassium aren’t in the toilet and cause problems. Thanks.
